摘要: Abstract Soot formation in the combustion of hydrocarbon fuels is net effect competition between molecular weight growth and destruction mechanisms involving free radicals. Chlorine addition to fuel can alter concentrations radicals a manner that enhances soot formation. In diffusion flames purely pyrolysis systems, presence chlorine increases fractional conversion carbon soot, while premixed well-stirred lowers critical equivalence ratio for onset These effects tend not be major importance systems unless substantial amounts are added. The has strong tendency go HO, which may or significantly lower concentration H atoms, turn affect OH O, depending on whether atomic Cl/H comparable much less than unity. observed qu...
